RAID-10
A RAID-10 is an example of a dual-level array and is created by
using two or more equal-sized RAID-1s to create a RAID-0.
Drive
The top level RAID-0 shares the load among the second level
RAID-1s, improving both read and write performance. Since
second level arrays are RAID-1, only half the total capacity of the
drives in the array is available.
